MB2011LS1W01-BE Equivalent & Substitute Parts

Part Overview

The MB2011LS1W01-BE is a pushbutton switch manufactured by NKK Switches, featuring SPDT (Single Pole Double Throw) circuit configuration with 6A AC and 3A DC current ratings at 125V AC and 30V DC respectively. This component is classified as obsolete, necessitating identification of active equivalent parts for new designs and ongoing production requirements. The switch employs panel mount rear termination with solder lug connections and yellow round button actuator, sealed with epoxy-coated terminals for environmental protection.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MB2011LS1W01-BE is determined by the following critical parameters:

Primary Matching Criteria:

• Circuit configuration: SPDT
• Switch function: On-Mom (momentary action)
• Current rating: Minimum 6A AC capability
• Voltage rating: Minimum 125V AC and 30V DC
• Mounting type: Panel Mount, Rear
• Termination style: Solder Lug
• Panel cutout compatibility: Circular configuration

Secondary Compatibility Factors:

• Operating temperature range overlap
• Electrical life rating
• RoHS and regulatory compliance status
• Mechanical life performance

The identified substitute parts MBN15LS1W01-BE, MPA106F, and MPE106F meet the primary electrical and mechanical matching criteria, though with variations in secondary parameters that must be evaluated for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

MPA106F and MPE106F (TE Connectivity ALCOSWITCH): These parts represent the most direct electrical equivalents to the MB2011LS1W01-BE. Both maintain identical SPDT circuit configuration, momentary switch function, and 6A AC / 125V AC ratings. DC current capability is increased to 4A with 28V DC rating, providing enhanced performance margin. Both parts are ROHS3 compliant and carry active product status, ensuring long-term availability and supply chain stability. The primary consideration is panel cutout diameter variance (6.35mm versus 6.50mm original), which may require mechanical adaptation depending on panel design. MPE106F provides additional splash-proof ingress protection and REACH compliance status, offering enhanced environmental resilience for applications requiring moisture resistance.

MBN15LS1W01-BE (NKK Switches): This NKK Switches alternative maintains manufacturer continuity and active product status. However, incomplete electrical parameter specification in available documentation limits direct confirmation of full compatibility with the original MB2011LS1W01-BE ratings. The bushing mount configuration differs from the panel mount rear termination of the original part, requiring mechanical redesign consideration. This option is suitable only when complete technical specifications can be verified through direct manufacturer consultation.

Frequently Asked Questions (FAQ)

Q: Can MPA106F or MPE106F directly replace MB2011LS1W01-BE without modification?

A: Both parts satisfy the core electrical requirements (SPDT, 6A AC, 125V AC, momentary function, solder lug termination). The panel cutout diameter difference (6.35mm versus 6.50mm) requires evaluation of panel tolerance and mechanical fit. No electrical modification is necessary if mechanical accommodation is addressed.

Q: What is the significance of the increased DC current rating in MPA106F and MPE106F?

A: The substitute parts provide 4A DC capability compared to the original 3A DC rating. This represents a performance enhancement that does not compromise compatibility; applications requiring 3A DC operation remain fully supported with additional margin.

Q: Why is MBN15LS1W01-BE listed as a substitute if specifications are incomplete?

A: MBN15LS1W01-BE is identified as a manufacturer-recommended alternative by NKK Switches. However, incomplete parameter documentation in the reference data prevents full technical verification. Direct manufacturer confirmation of electrical ratings and mechanical compatibility is required before selection.

Q: What is the difference between MPA106F and MPE106F?

A: Both parts share identical electrical specifications (SPDT, 6A AC, 4A DC, 125V AC, 28V DC). MPE106F provides splash-proof ingress protection and REACH compliance status, making it suitable for applications with moisture exposure or regulatory requirements. MPA106F lacks specified ingress protection but remains suitable for standard panel-mount applications.

Q: Are there temperature range limitations with the substitute parts?

A: The TE Connectivity alternatives operate within -20°C to 80°C, compared to the original -30°C to 85°C range. Applications requiring operation below -20°C or above 80°C require verification that the substitute parts meet specific environmental requirements.

Q: What is the electrical life difference between the original and substitute parts?

A: The original MB2011LS1W01-BE specifies 25,000 electrical cycles. MPA106F and MPE106F provide 50,000 electrical cycles, representing doubled operational life expectancy. This enhancement supports extended service intervals in high-cycle applications.
